CARPET-CLEANING. MACHINE.

Specification of Letters'Patent. Patented Feb. 111, 1919..

Application filed August 26, 1918. Serial No. 251,493.

To all whom it may concern:

Be it known that 1, ANDREW J. VWEIS, a

citizen of the United States, residing at Dayton. in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Carpet-Cleaning Machines, of'which the following is a specification. 7

This invention relates to an apparatus for cleansing carpets, rugs, etc. The object of the invention is to provide an eflicient and satisfactory machine for doing this work. The details or particulars of the invention are hereinafter described in connection with the accompanying drawings and the essential elements thereof are embodied in the sub joined claim.

Referring to the accompanying drawings in general terms, Figure 1 is a top plan view of a carpet cleaning machine constructed in accordance with my invention. Fig. 2 is a side elevation thereof, Fig. 3 is an end elevation with parts of the frame broken away. Fig. 4. is a detail view of the manifold through which the'liquids are discharged to the cleansing brushes as they rotate over the carpet or rug, and Fig. 5 is an enlarged sectional viewof one of the jets or spray nozzles of the manifold, the same being on the line 55 of Fig. 4. l

In a more particular description of the'invention similar reference characters will be employed to indicate corresponding parts in the several views of the drawings.

The machine is of a portable character and consists of frame parts of which are indicated by 1, such parts being the side frame members which are united by several cross frame members 1 the Whole constituting a light and rigid frame work, the said parts being preferably made of suitable light angle iron. The frame thus constituted is supported on easy running wheels 2 the axles 3 of which are journaled in suitable bearings provided therefor in the frame. A motor 10 of the electric type is supported on the middle portion of the frame by means of standards 25 which rise from and are made fast to the frame and provide bearings for the journals of the motor shaft 12. The motor 10 is inclosed by a hood 11 and the said motor is fed with current through a common form of flexible conductor (not shown). J Mounted between the said frame membersl are two brushes 4 and 5. These brushes have their shafts 26 j ournaled in the lower ends of drag arms 6 the upper ends of sald arms being loosely, connected to the motor shaft 12.. The brushes 4 and 5 engage the carpet or rug as the machine is propelled thereover by means of the handle 27 which is connected to one end of the frame. The said brushes 4 and 5 are adjustable with reference to the carpet or rug by means of adjusting rods 22. The lower endsof these rods 22 are connected, to yokes 28 which extend above and parallel with the brushes and have their ends connected to the brush supporting arms 6. The upper ends of the adjusting rods 22 are screw-threaded and pass through an opening in the middle portion of each of the transverse bars 28 which are parts of superstructures'which. extends from each end of the frame and support the containers 8 and 9. The super-structures extending from the main frame of the machine consists each of parts 7 with intermediate and inner braces 7 Angle irons 7" are attached to the upper portions of the frame members 7 and pro vide supports for the containers 8 and 9 which are made fast thereto in any suitable way. One of these containers is designed to contain liquid soap and the other is designed to contain gasolene which is applied after the liquid soap. The liquid soap is first applied to the carpet or rug during the cleansing process and after this is done and the carpet is sufiiciently cleansed the gasolene is discharged to its respective brush. The liquid soap is discharged to one of the brushes, for example,- brush 5, through a pipe 15- which extends from the container 9 and is controlled by a valve 17, said valve control- .ling the passage to the manifold 18 which brush through the action of centrifugal force. It will be understood that as the brush revolves it has a tendency to throw the liquid ,away from it but coming in contact 'with the fender or guard 24 the vefiect is to direct it back onto the brush. The fenders 24 are supported in proximity to the brushes 4 and 5 and on the outer sides thereof by brackets 29 which are secured to the brush drag arms 6. The other container, for example, 8, is designed'to hold gasolene which is fed to the brush it through a pipe 16 controlled by a valve 17 and provided with-a manifold such as is shown in Fig. 4. The brushes are revolved by means of belts 13 which are driven from pulleys 30 on the motor shaft 12 and connect with pulleys 31 on the shafts of the brushes. One of the belts 13, it will be observed, is crossed in order to drive its respective brush in the opposite direction to the drive of the other brush. A dust and dirt receptacle 20 lies between the two brushes 4 and 5. This dust receptacle is provided with a partition 21 and the outer sides thereof are open to receive the dust and dirt swept from the carpet in the operation of the machine. This receptacle 20 is suitably mounted upon the frame of the machine in a manner that enables it being removed whenever it becomes necessary to empty the same. The machine is manipulated by grasping the handle 27. The length of the electric conductor which feeds the motor and which is omitted from than is necessary during the operation of the machine. The hood 11 is provided as a means for safeguarding the motor and preventing tampering therewith. Looking at tact of the brushes 4 and 5 with the carpet or rug is effected through the adjusting rods 22. Having described my invention I claim:

In a machine of the character specified,v

the combination of a portable frame, elevated frames supported thereon, containers supported on said elevated frames for holding the liquids to be used in the cleansing operation, brushes mounted on adjustable supports, adjusting means connected with said supports and with the elevated frames, a motor driven shaft connected with the brush shafts, a dirt receptacle between the brushes for receiving the sweepings therefrom, and fenders extending from the adjustable supports and inclosing the outer Eidcies of the brushes, substantially as speci- In testimony whereof I aflix my signature.

ANDREW J. WEIS.
